- Y oannonarrine APPARATUS.

To all whom t may concern:

Be it known that we, 4REUBEN LIGHTER and LEWIS LEWENHOFF, a subject oft-he Czar of Russia and a citizen of the United States, residing'atNew York, county and State of `New York, and in New York, borough of Brooklyn, countyl of Kings, and State of New York, respectively, have invented a certain new and useful Improvement in- Carbonating Apparatus, of vwhich the fol lowing is a full, clear, and exact specificasigned to be employed in conjunctionwith I of the funnel-shaped partitions.

soda fountains, or similar apparatus for carrying a supply of carbonated water to be dispensed therefrom for drinking purposes, and wherein is employed ajfilter for clarifying the water'as it is admitted into' the tank and before t-hewater is charged with gas, thereby dispensing with the requirement of using a special filtering lapparatus.' Another Vobject of the invention is4 to provide the tank with a lining which will not rust or corrode from the action of the carbonated water thereon; and a further object ofthe invention vis toprovide a form of tank which is susceptible of being made so as to be very durable, in orderto safely withstand a high pressure of the'carbonating gas, but which is comparatively light in weight. l

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this speciiication in which similar characters lof reference indicate corresponding part-s in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims.

In the drawings, l1`igure 1 is a `longitudinal vertical section through one form of soda fountain tank embodying our invention. Fig. 2, is a section taken on the. line II-.1I of F ig. 1. Fig. 3 is a vertical side view, partly in section and partly broken away, of the filter employed in conjunction with the tank. Fig. 4 is a top plan of one Fig. 5 is a sectional view,partly in detail, of the valve of the tank, and Fig, 6 is a fragmentary Speccationof Letters Patent.

view, part-ly in section, showing the manner of 'fastening the sections of the body of the tank together. i I

The tank 10 hasv a body, or shell 11 composed of twoy sections, or members 12 and l13 which are somewhat similar in shape, each being parabolicv in form or substantially Ushaped 'in cross section. Upon the opposed edge of theopen end of each of the sections, or members 12 and 13 is an annular flange 14 and 15, and circumscribing a part of the curved end of the section 13 is the usual flange 16 which serves to support Athe tank'when disposed in a vertical position. Througheach of the annular ianges 14 and 15 are a number of corresponding spaced openings 17 and 1S, and to provide an air-tight and water-tight joint between said sections a packing, or gasket, as 19, is I inserted between thel opposed surfaces of said annular iianges.

In order t-o permit the flanges 14 and 15 to be firmly secured for holding the sections 12 and 13V together a ring 20 is` so that bolts, or the like may be passed i therethrough for tightly fastening the parts together.

As is incident to the usual form of soda fountain tanks, we prefer to make both of the sections 12 and 13 of the body 1l of seamless steel whichmay be formed by any well known stamping process so as tobe snflicicntly durable to withstand a high pressune, but will be comparatively light in e weight. Serving to prevent the inner surface Vof the tank from rusting or corroding, both of the sections 12 and 13 of the body 11 is lined with aluminum, or other material, as 25, which is not susceptible of being affected by contact with water, or carbonaceous gases. i v,

Within the body 11 ofthe tank is a device 26 adapted to be employed for filtering water admitted to the tank throughv the Ine-lAV i vprovided with spaced perforations 33, and

the large open end of each of said partitions is covered by. a cap 34 which alsol has a plurality of spaced perforations 35 there-` through. The'funnel-shaped partitions are positioned so that the apex of one rests centrally upon the perforated cap of the partition underneath it, and in the chambers, orf

inclosures 36 thus formed is a required quant-ity of filtering material 37, such as small particles of stone, or other suitable,

substances. Centrally of the top of the -casing 29 is a neck 38 whereby an inlet 39- is provided. The neck 38 is eXteriOrly threaded so that a nut 39a may be screwed thereon for holding the filtering device 26 against displacement within the body 11 when said neck is disposed through an opening 40 provided inthe top ofthe section 12 of the body, and to provide a water-tight joint be# tween the top of the casing 29 and the lining 25 is a packing, or gasket 41. Centrally through each of the funnel-shaped. partitions 31 is -an opening 42 so that all of the openings will 'be in alinement when the partitions are assembled, as shown in Fig. 1,'

and guided through said openings is a pipe 43 which is Aof suflicient length to extend through the filtering device to nearly the inner surface of the bottom of the tank. The

casing 29, the funnel-shaped partitions 31,

and the pipe 43 are preferably made of aluminum, though any other non-rusta'ble,

usual or any preferred type having av body 45, and in the lower part of said body is a vertical passage 46. Transversely through .the body 45 of the .valve are oppositely disposed passages 47 and 48 which counnunicate with the passage 46. The transverse passage 47 serves as an inlet for admission of the gas with which the water in the tank is charged and also serves as an outlet for the carbonated water when ready to be dispensed.. The mouth of the transverse pas-` sage 47 may be closed by a cap 49, and in the transverse passage 48 is a rotatable needle vaivc, or cock 50 "adapted, to be revolved by a'hand-wheel 51. The cock 50 is adapted to control the opening and closing of the passage 47, and ihexawby also controls the vertical passage 46. Through the bodyi45 from its top to its bottom is a passage 52. In the lower part o-f the passage 52 is a tube 53, and in the upper part of said passage may be placed a nipple to permit the pipe 27 to be connected to the 'valve whereby water from its source of supply may be delivered tov the filtering device 26 through t-he passage `52 and throughthe tube 53. The water will then be filtered by flowing through the perforated funnel-shaped partitions-31, through the clarifying material4 37, and into the tank. After the passage 52 is s litably closed, and the cap 49 is removed from the body of the valve 44, the carbonating gas is admitted through the transverse passage 47, through the vertical passage 46 and through the pipe4 43. A The water is charged with the gas by agitation in the usual manner of rocking the tank while the'gas is .be-` ing admitted thereinto. The tank is then closed by the cock 50 and the carbonated water may afterward vvbe dispensed by rotating the cock .50 to Vopen-the passages 46 and 47 whereby the p'ressureof the carbonated water will force it to iow from the tank through the pipe 43 andI through the passages 46 and 47.

-ln the foregoing description we have embodied the Apreferred form of our invention, but we do not wish to be understood as limiting ourselves thereto, as we are aware that modifications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention, therefore we reserve to ourselves the right to make such changes as fairly fall within the scope thereof.
